Tamahagane razor with rubies.
@32t In the other thread you mentioned being focused
This one had my nerves strung tight.
First I had 4 holes that were spaced exactly right, relative to each other, and in the middle of the tang.
Then I had to sink the circumference holes right over the guide holes, on both sides, to the right depth.
And then drill all the way through with a slightly smaller drill while not destroying the ridge inside the hole.
There are so many ways this can go wrong it's not funny.
